This week, a bold initiative by the U.S. Department of Health and Human Services (HHS) sent shockwaves through the food industry: it’s finally time to clean up the food dye aisle. Health Secretary Robert F. Kennedy Jr. and Food and Drug Administration (FDA) Commissioner Dr. Marty Makary announced plans to remove several artificial colorings from the American food supply—especially those saturating ultraprocessed snacks like chips, candy, and breakfast cereals. Their reason? Mounting concerns over how these additives may be impacting children’s health.

Makary didn’t mince words at Tuesday’s press conference. He linked these widely used dyes to a host of worrying issues—from obesity and diabetes to behavioral disorders like ADHD and even cancer. The message was clear: America’s kids deserve better than the rainbow-colored risks hiding in their snacks.

Which Dyes Are on the Chopping Block?

The FDA identified eight specific synthetic dyes they plan to phase out: Blue No. 1 and 2, Citrus Red No. 2, Green No. 3, Orange B, Red No. 40, and Yellow No. 5 and 6. Some of these, like Citrus Red No. 2 and Orange B, are not commonly used today. However, others like Red No. 40 and Yellow No. 5 are staples in brightly colored candies and drinks.

But how exactly will this transition happen? While the FDA says it will formally begin revoking authorization for the lesser-used dyes, the remaining ones fall under a voluntary agreement made between Kennedy and major food manufacturers. Whether this handshake deal leads to real change remains to be seen.

The timeline is ambitious—Makary said the process should be complete by the end of 2026. But given the voluntary nature of most of the action, enforcement is still a question mark.

The Science Behind the Concern

Research on food dyes and their impact on health is a mixed bag. Several small studies—like a notable 2007 trial from the U.K.—have shown that certain food colorings (particularly Yellow No. 5 and No. 6) can cause increased hyperactivity and reduced attention spans in children. A more recent 2021 review by scientists in California examined 27 studies and found that synthetic dyes like Blue No. 1, Green No. 3, and Red No. 40 may alter children’s behavior.

Yet despite these findings, experts urge caution. Many of the existing studies are short-term, small-scale, or involve combinations of dyes, making it difficult to isolate the effects of any single ingredient. Some researchers say the long-term consequences of dyes remain understudied, especially since they tend to exit the body quickly.

“There’s evidence of a connection between dyes and behavioral issues in some children, but this isn’t the silver bullet for solving childhood obesity or ADHD,” said Dr. Emily Barrett, a biostatistics expert at Rutgers University.

More Than Just Dyes: The Bigger Picture

Nutritionists argue that focusing solely on dyes might overlook the bigger issue: the overall poor nutritional quality of ultraprocessed foods. These foods often combine artificial colors with high amounts of sugar, sodium, and saturated fat—all contributors to rising rates of childhood obesity, Type 2 diabetes, and heart disease.

“The food dyes might be the flashy part, but they’re not the whole story,” noted Lindsey Smith Taillie, a nutrition professor at the University of North Carolina. “Removing them won’t suddenly make ultraprocessed foods healthy.”

The food industry, for its part, has long defended the use of artificial dyes, citing safety assessments by regulatory bodies. But public pressure is mounting, especially from advocacy groups like the Center for Science in the Public Interest, which has been pushing for dye bans for decades.

Natural Alternatives on the Fast Track

To support manufacturers in the transition, the FDA is fast-tracking approval of four natural dye alternatives: calcium phosphate, Galdieria extract blue, gardenia blue, and butterfly pea flower extract. While promising, these natural options will need rigorous testing to ensure safety and stability in different food products.

Still, experts caution that data on these alternatives is limited. “We’re moving in the right direction, but we need more research on these replacements too,” Dr. Barrett added.

A First Step, Not the Final Answer

In the fight to make kids’ food safer and healthier, the removal of synthetic dyes is a welcome step—but it’s far from the final one. It signals a broader shift in how America thinks about food, health, and what we allow in the products children consume daily.

As Secretary Kennedy pushes for more research and cooperation from the National Institutes of Health, parents, educators, and health professionals are watching closely. Because when it comes to our children’s health, every ingredient—and every choice—matters.
